Consider the given statement:

8+3.4=3.4+8

We have to identify the property used in this statement.

1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that a+(b+c) = (a+b)+c. This property is not used in the given statement.

2. Inverse property of addition: A number 'a' is said to have an inverse '-a' if a+(-a)=0. This property is not used in the given statement.

3. Inverse property of multiplication: A number 'a' is said to have an inverse '\frac{1}{a}' if a \times \frac{1}{a}=1. This property is not used in the given statement.

4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that a+b = b+a.

In the given statement, 8+3.4=3.4+8

which is expressed as 8+12 = 12+8, this statement holds commutative property of addition as whether 8 is added to 12 or 12  is added to 8, the result is same.

So, Commutative property of addition is illustrated in this statement.

The diameter of a circle is 22 miles. What is the circle's area? Use 3.14 for pi.. Single choice.
Sonbull [250]

Answer:

379.94 mi²

Step-by-step explanation:

The area of a circle can be figured out with this formula: πr² (3.14 is π here, as it says in the directions).

We know the diameter is 22 miles. Divide that by 2 to get a radius of 11 miles.

The equation now becomes

3.14(11²)

11 squared is 121.

3.14(121)

I recommend splitting the 121 into 100, 20, and 1.

(3.14 * 100) + (3.14 * 20) + (3.14 * 1)

Multiply 3.14 by 100, 20, and 1.

314 + 62.8 + 3.14

Add 314 and 62.8.

376.8 + 3.14

Add 376.8 and 3.14

379.94 mi² is the area of a circle with a 22-mile diameter.

Jim thinks of a number (n). He adds 5 to the
Karolina [17]

Answers + Step-by-step explanation :

a) the equation should be:
7(n + 5) = 91 since you first add 5 to n and then multiply it by 7. The answer is 91 so that is on the other side of the equal sign

b) we can solve our equation to find for n, the number jim thought of

7(n + 5) = 91
I will use the distributive property.

7n + 35 = 91

Subtract 35 on both sides

7n = 56

Now divide 7 on both sides to find n

n = 8

The number Jim was thinking of was 8! this should be correct, hope this helps!
